An elevator car starts on the second floor of a building 28 feet above the ground. The car rises 3.11 feet every second on its way up to the 11th floor. Assuming the car doesn’t slow down or make any stops, how long will it take the car to reach a height of 85 feet above the ground?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
